[Koha] Koha 3.16.2: open external link in a separate window

Hello Koha, I life in Germany and use Koha 3.16.2 in my private home. I have to link some additional informations from a wiki in the biblioitems. In this case I use the field "URL", but the weblink in this field opens (in OPAC and Admin) in the same browser tab. Is there a possibility to open a external weblink in a biblioitem in a separate browser tab? Thanks for this usefull programm, Koha! Sebastian ___ mailto: sebastian.krieg@tuz-eisenach.de
